The concept of implosion comes from explosion , although with the replacement of the prefix. An explosion is the process that develops when, due to a rapid increase in pressure, energy is released violently , releasing gases, lights and heat, making noise and breaking the object where it was contained.
In the case of implosion, it occurs when in a body register a pressure lower than the outside , which causes its walls to break inwards. Therefore, in colloquial language, it is often said that an implosion is a kind of explosion inward : the element it implies collapses on itself by an external force.
A submarine For example, it may suffer an implosion if it is submerged too much, beyond the limit that the ship can withstand. In that case, when the Pressure The water is very high because of the depth, implosion occurs and the submarine is compressed abruptly and with great noise. It is suspected that this is what happened to the ARA San Juan , a submarine of the Argentina Army that disappeared in November 2017 at Atlantic Ocean with 44 people on board.
The idea implosion is also often used to refer to a method that allows demolish a building, a tunnel, a bridge, etc. However, it is not technically an implosion since there is no internal and external pressure difference, but the support points are removed or weakened so that the structure cannot withstand the force of gravity and falls on itself .
